1. Evaluation of Woodmer/plastic composites
University essay from KTH/Fiber- och polymerteknologiAbstract : Plast ger otroliga möjligheter i form av stor variation för materialanvändning. Tyvärr sker det dock på bekostnad av miljön då de ackumuleras i naturen. En kompromiss mellan hållbarhet och fortsatt plastanvändning skulle kunna vara att använda biomassa som fyllnadsmaterial i plastkompositer istället för plast. READ MORE

2. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish
University essay from Uppsala universitet/Tillämpad mekanikAbstract : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). READ MORE

3. Wet spinning of carbon fiber precursors from cellulose-lignin blends in a cold NaOH(aq) solvent system
University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)Abstract : Carbon fiber (CF) is predominantly produced from fossil-based sources and is therefore an area of interest for further development towards a more sustainable society. The purpose of this thesis work was to investigate the possibility of producing precursor fibers (PFs) for CF production from a blend of renewable cellulose andlignin. READ MORE

4. Synthesis and Investigation of Nitrile-Containing Polymers Inspired by Lignin
University essay from Lunds universitet/Centrum för analys och syntesAbstract : The lignin-inspired derivatives coniferyl aldehyde and sinapyl aldehyde were used to prepare nitrile-containing methacrylate monomers with the aim to synthesize bio-based polymers exhibiting high glass transition temperatures (Tgs). The aldehydes were initially transformed to the corresponding nitriles and then underwent methacrylation before being polymerised by free-radical polymerisation. READ MORE

5. Evaluation of the recyclabillity of a lignin-based biopolymer
University essay from Luleå tekniska universitet/MaterialvetenskapAbstract : The use of plastic materials has changed the packaging industry, the construction industry, the automotive industry, and many others drastically. Plastics are also abundant in our everyday life. However, its downsides in the society are undeniable and are starting to get attention from law makers, the general public and industries alike.
